Description
Technical field
The present invention relates generally to battery, and is particularly related to lead-acid battery.
Background technology
Typical battery comprises one or more electrochemical cell that are electrically connected and provide to battery electric power at inside battery.These battery units generally comprise four kinds of basic modules: receive the positive pole (negative electrode when anode during charging and discharge) from the electronics of external circuit when battery unit discharges; When discharging, battery unit discharges the negative pole (anode when negative electrode during charging and discharge) of electronics to external circuit; The electrolyte (being present in usually in solution or the pastel) that provides a kind of mechanism that electric charge is flowed between positive pole and negative pole; And the one or more dividing plates that make positive pole and negative electricity insulation.Because the electrochemical relationship between these assemblies makes this structure can make battery unit produce electric energy.In case the generation electric current, electric current just flow to terminal from positive plate by electrical current carriers, is sent to external circuit from terminal, gets back to battery (generally by another electrical current carriers) by the terminal that is connected with negative plate then.
When the rechargeable character of needs, lead-acid battery receives an acclaim.Because abuse is had high tolerance and relative low manufacturing cost, especially when battery weight was not major consideration, this battery was desirable especially for requiring rechargeable application.Thus, lead-acid battery is often used in to automobile and other vehicles provide power, because these external environments can be very abominable and abuse miscellaneous can be occurred.Lead-acid battery also often is used in when power network can not use and provides in the back-up system of power.
Most of lead-acid batteries mainly utilize identical basic electrochemical reaction to produce electric energy, and generally use identical active material.Electrochemical reaction is as follows:
Negative electrode: PbO
2+ SO
4 -2+ 4H
++ 2e
-→ PbSO
4+ 2H
2O
Anode: Pb+SO
4 -2→ PbSO
4+ 2e
-
At anode, metallic lead and sulfate ion (SO
4 -2) send out and should generate lead sulfate (PbSO
4).At negative electrode, lead oxide (PbO
2) and sulfate ion (SO
4 -2) reaction also generates lead sulfate.Electronics is provided by anode, and the external circuit of flowing through is received by negative electrode.
In practice, typical lead-acid battery comprises anode layer and the cathode layer that multilayer is stacked.Usually, it is set to a kind of in following two kinds of structures: the rectangular band of laminated plate or screw winding.In arbitrary situation, all to isolate mutually between anode layer and the cathode layer by carrier ring, carrier ring is made by electrical insulating material (glass fibre bedding and padding etc. are typically arranged).The sulfuric acid solution of dilution is used as electrolyte usually provides sulfate ion.
The laminated plate pattern of lead-acid battery generally comprises a plurality of anodes and the negative electrode that alternating sequence is arranged in the lamination of separating by carrier ring.In other words, the typical layout comprises a minus plate, a dividing plate, and a positive plate, another dividing plate, second minus plate, the rest may be inferred.Some lead-acid battery cells comprise 29 stacked by this way minus plates and positive plate.
In order to utilize by the electric energy that electrochemical reaction produced takes place on the battery lead plate, parallel with one another between the minus plate, also parallel with one another between the positive plate.A kind of common technique that connects pole plate is at an edge of each pole plate outstanding tab to be set.Tab is arranged on the identical position of each minus plate, makes can align between the tab when stacked at pole plate.Tab is connected on the conduction connecting band, promptly in turn is connected to battery terminal.Similarly the tab of alignment is given prominence to and is passed through a connecting band from positive plate and connects, but these tabs are set on the different position of positive plate to avoid and the mutual interference mutually of anode connecting band.For example, a example to this structure has been described in the U.S. Patent No. 4383011 of McClelland etc.
Lead-acid battery with this design in use can run into the problem of vibration resistance and durability aspect.As mentioned above, because lead-acid battery is generally very solid, often be used in the rugged environment.Therefore, they to be subjected to strict test, especially impact, bump, collision and vibration repellence (as a typical test, referring to VG96924-2, BS6290 the 4th part, IEC).In some cases, fracture occurs in the tab of positive plate and the junction between the connecting band.This zone of positive plate can since below being used for of taking place of tab surface protected the oxidation reaction of the metallic lead (Pb) of bulk (promptly form PbO
2) and become fragile.PbO
2Layer is more crisp relatively, can cracking under the shear action that applies during the vibration-testing.These cracks can make following metallic lead come out then, and oxidized thereupon.This pattern in generation oxidation behind the cracking constantly repeats to rupture fully from pole plate up to tab.
Summary of the invention
The objective of the invention is to battery unit and Battery And Its Manufacturing Methods, when battery is subjected to vibrating check and the detection of other strict mechanics, help the resistance to fracture of junction between positive plate tab and connecting band.As a first aspect of the present invention, the method for making battery comprises one, and it has positive plate and negative plate alternately for battery provides the initial step of battery unit, wherein between each pole plate insulated carrier ring separately, positive plate and negative plate are stacked mutually.Each positive plate all comprises the tab outstanding from adjacent positive plate top, alignment usually between the tab of positive plate.Each negative plate all comprises outstanding tab, alignment usually between the tab of negative plate.Next, this method comprise with the conduction connecting band be attached on the outstanding tab of positive plate.This method comprises that cladding material is applied to positive plate gives prominence to the tab part top adjacent with positive plate (for example by topple over adhesive material on anodal connecting band then, it is scatter and drip to positive plate, and on the tab and top and dividing plate of common negative plate), cladding material is hardened provides one to be attached at the outstanding tab of positive plate and negative plate and the cover layer on the adjacent upper.This method can provide a kind of battery unit, and wherein hardened and/or prevent oxidation in the junction between positive plate tab and the connecting band, improves the performance in the mechanical test thus.
On the other hand, the objective of the invention is to a kind of battery, it comprises: shell; A plurality of positive plates that replace and negative plate; Two conduction connecting bands; With a cover layer.Separated stacked being placed in the shell between each positive plate and the negative plate by the electric insulation baffle layer.Each positive plate has the outstanding tab that extends out from the adjacent upper of this positive plate, the tab general alignment of positive plate, and each negative plate has outstanding tab, the tab general alignment of negative plate.A conduction connecting band is mutually attached with the outstanding tab of positive plate, and another conduction connecting band is mutually attached with the outstanding tab of negative plate.The adjacent upper of outstanding tab part of cover layer (for example making by adhesive material) covering positive plate and positive plate (and, generally also cover negative plate and dividing plate).
